Step 1

Preheat an offset smoker for cooking at 250 degrees F.

Step 2

Rub pork collar generously with dry rub. Place pork in smoker and cook, brushing with Honey BBQ Glaze every hour, until internal temperature reaches 150 degrees F, about 5 hours.

Step 3

Let rest for 15 to 20 minutes, then slice into 1/4-inch slices.

Step 4

Meanwhile, put tomatoes in a pan, drizzle with 4 to 6 tablespoons olive oil, and sprinkle each side with dry rub. Cover with foil and smoke in smoker for 1 hour.

Step 5

Meanwhile, place onions in a medium saute pan with 2 tablespoons olive oil. Cook over low heat until onions are caramelized, soft and golden brown, 1 to 2 hours. Mash onions into a chunky paste.

Step 6

Slice open bolillo bread. Melt butter in a large saute pan or comal over medium-high heat. Place bolillo bread pieces in the pan cut-side down and cook until golden and toasted. Drizzle 2 tablespoons olive oil into the same pan. Place sliced pork collar into pan. Drizzle each side with Honey BBQ Glaze. Sear each side of pork for 2 to 3 minutes. (You may also use this same pan to warm up cooled smoked tomatoes, if needed.) Build 6 open-faced sandwiches, spreading a generous layer of caramelized onion paste on each piece of bread, layering the pork on top, layering on smoked tomatoes and drizzling with Honey BBQ Glaze.

Step 7

For the BBQ sauce: Preheat an offset smoker for cooking at 225 degrees F.

Step 8

Whisk together the ketchup, vinegar, mustard, onion, Worcestershire, pepper, dry rub and granulated garlic in a stainless steel or cast-iron pot until smooth. Place in smoker to cook until darkened, medium-thick and the onions have softened, 4 to 6 hours. (Alternately, cook BBQ sauce in a pan on the stovetop over low heat, covered, 4 to 6 hours.)

Step 9

For the glaze: Whisk together honey with 2 1/2 cups BBQ sauce until smooth and creamy (save the remaining BBQ sauce for another use).
